FIELD SIGN Filed March 22, 1929 Patented Oct. 14, 1930 UNITED STATES FIELD"sien"` Application led March 22, 1929. lSerial No. 349,0178.

This invention relates to improvements in signs, particularly of the class of signs used for road markers, and like purposes. The main objects of the invention are to provi-de a neat appearing, strongly constructed sign of simple, economical construction, and which is especially adaptable for quantity production, and to provide an improved and substantial type of mounting for signs.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which,-

Fig. l is a front elevation of a sign;

Fig. 2 is a side elevation of the upper portion of the sign;

Fig. 3 is a detailed sectional view taken on the line 3 3 of Fig. l;

Fig. 4 is a detailed section of the upper end, taken on the line 4 4 of Fig. 2;

lig. 5 is taken on the line 5-5 of Fig. 2; an

Fig. 6 is taken on the line 6-6 of Fig. l.

Referring to the drawings, the post l is made of pipe, of any suitable size, and thev lower end is preferably set in a concrete block 2 which is embedded in the earth.

On the upper end of the post l is a reducer 3 which is threaded and the vertical pipe 4 of the tubular sign frame is made smaller than the post, and is threaded into the upper end of the reducer 3. A cap or finishing piece 5 is mounted in the upper end of the pipe 4, and is provided with an overhanging circumferential shoulder to keep moisture out of the interior of the pipe.

The cross arm 6, smaller in diameter than the pipe 4 (usually about one-half) is inserted through a hole drilled transversely in the middle of the pipe 4, as best shown in Fig. 6. Preferably the Cross arm is also of tubing, to obtain the desired strength with little weight. In order to provide coplanar fastening surfaces for the opposed sign plates 7, T-shaped distance pieces or blocks 8 are mounted in the ends of the cross member 6. The distance pieces are provided with plugs 9 which are inserted in the ends of the pipe, and have a hole extending through the body thereof, which lies in a horizontal plane, with the end faces, to which the sign is secured, flush with the sides of the vertical pipes 5.

The sign plates 7 are preferablysquare or diamond-shaped and are mounted on' the opposite sides of the tubular frame by means of bolts 11, through the top and bottom corners, passing through the vertical pipe member A5, and by bolts l2 through the side corners, passing through the distance pieces, or blocks 8.

Since the faces of the distance pieces or blocks are flush with the sides of the pipe 4, the plates are rigidly braced when in position, which enables the use of porcelain enamel sheets if desired. When the signs are assembled on the tubular frame, a very rigid and light structure is formed. The sign plates serve to hold the frame members 4 and 6 rigidly in angular relation, and the relatively diagonal arrangement of the tubular members holds the plates extended against chance blows, especially at the sides which are most exposed.

In the construction shown no special machine tool work is required in production. The post l is cut to length and threaded on Vone end to receive the reducer and vertical pipe 4 of the frame. The pipe 4 requires only drilling for the bolts and the cross member 6, while the blocks 8 and the cap 5 may be cast sufficiently accurate in size for use without any further processing.

Although but one specic embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention, as defined-by the following claims. y

I claim:

l. In a sign, a vertical frame pipe, a cross arm inserted through a hole in `the pipe, blocks secured in the ends of the cross arm, and sign plates secured to the opposite sides of the pipe and cross arm by boltsthrough the pipe and bolts through the blocks.

2. A sign comprising: a vertically mounted tubular post; a frame comprising a pipe secured in the end of the post and having a transverse hole through the middle, a tubular cross arm inserted through salu hole, and

blocks of a thichness equal to the diameter of the pipe secured in the ends of the cross arm;

and sign plates secured to the opposite sides of the frame by bolts passing through the 5 pine and through each of the blocks.

8. A sign comprising: a post; a frame comprising a pipe secured vertically in the end oi the post, said pipe having a transverse hole through the middle, a pipe inserted through H, said hole, and blocks secured in the ends of the second pipe; and sign plates secured to the opposite sides of the frame by bolts through tne blocks and through the vertical pipe.

I. A sign comprising a pair of opposed sign plates, a pipe extending vertically' between said plaies and secured thereto at the top and bottom, a cross arm extending transversely through said pipe and having distance blocks at its ends to space and secure the sides of the plates.
